Alert: The Allium Leafminer is active!

As we roll into the fall season that means it is time again to be on the look out for Allium leafminer adults. We have just received reports this week indicating fly emergence.

Most of the feeding damage we are seeing seems to be focused on green/bunching onions but we have also found adults within leek plantings. We suggest growers immediately start their chosen management method for the fall allium crops.
